EC hushkit ruling faces fierce opposition, Issue 3 Jan/Feb 1999

Proposals by the EC to cap hushkitted aircraft operating in EC airspace
are being attacked on several fronts. Objections have been voiced
about the absence of an economic impact study prior to the ruling,
the EC breaking with agreed ICAO noise standards, there being no
definition of what noise emissions the EC requires and Chapter 3
modified aircraft often having lower noise emissions than new aircraft.
